General technological flow for electronic grade ultra pure water:
(Water quality is in accordance with the ASTM standard - Standard of Water Quality for Ultra Pure Water for Electronic Industry - Grade IV)
● raw water → raw water pump → sand filter → carbon filter → fine filter → reverse osmosis → water tank → positive bed → negative bed → mixed bed → purified water tank → pure water pump → ultraviolet sterilizer → refined mixed bed → microporous filter → water users
● raw water → raw water pump → sand filter → carbon filter → fine filter → Primary reverse osmosis → pharmaceutical adding pump (PH adjustment) → middle water tank → Secondary reverse osmosis → purified water tank → pure water pump → ultraviolet sterilizer → 0.22μm microporous filter → water users
